In C (and you've tagged this as C), that's pretty much the only way to initialize an array of char with a string value (initialization is different from assignment). Examples also show how to control putting arrays in RAM or non-volatile memory and selecting which data files to use for initialization. From the above examples, we can say that a string array is very much similar to a list of string. Example: Below code snippet initializes the element at 0 row index and 0 column index by 10. arr[0][0]=10; String arrays: The Two-Dimensional, array of strings can be initialized as follows: A string is a series of characters followed by a string terminator ('\0').An empty string ("") consists of no characters followed by a single string terminator character - i.e. Joined Jul 28, 2002 Messages 23. This blog will run you through 3 ways to initialize a JavaScript Array with conditional elements. Array of Pointers to Strings # An array of pointers to strings is an array of character pointers where each pointer points to the first character of the string or the base address of the string. We need to create an array with size 3. string[ ] student = new string[ 3 ]; The first part “string” defines the data type of the array, then we provide the array name.
